Evidence Guide for Nut Allergy Claims

What evidence do I need after a restaurant allergic reaction? Medical records proving your reaction + receipt showing where you ate = valid claim foundation. Missing key evidence? Three out of four people have more than they think.   

Do I have enough evidence for a nut allergy claim?

Most people who contact us believe they lack sufficient evidence. After 17 years handling nut allergy claims, we know imperfect evidence doesn’t mean no claim. The guide below shows what actually matters.

You need medical evidence of your reaction (A&E records, GP notes, even pharmacy receipts), proof you ate at the establishment (receipt, booking, delivery app), and ideally photos of your symptoms. But here’s what most people don’t know: you can build a strong claim even if some evidence is missing. Since 2007, we’ve learned which evidence actually matters to insurers—and it’s not always what you’d expect.

This Comprehensive Guide Covers:

• The evidence hierarchy – What’s critical, what’s strong, what’s just helpful
• Medical records that matter – From A&E gold standard to pharmacy receipts
• Physical evidence preservation – Packaging, food samples, receipts, app orders
• Building strong claims with imperfect evidence – What works when “perfect” proof is missing
• How we obtain records you don’t have – Subject Access Requests and beyond

This Guide Is Essential If You:

• Suffered a nut allergy reaction and aren’t sure what evidence you have
• Threw away packaging or didn’t photograph symptoms
• Didn’t go to hospital immediately but still had a reaction
• Were told by others your claim won’t succeed due to lack of proof

Understanding Evidence in Nut Allergy Claims

The Legal Framework – England and Wales Only

Food businesses owe you a duty of care under the Food Safety Act 1990 and Food Information Regulations 2014. These regulations apply to all food allergy reactions – learn more about making a nut allergy compensation claim. When you inform them of a nut allergy, that duty intensifies. They must ensure your food is safe. If they breach that duty—through contamination, mislabelling, or poor allergen management—and you suffer harm as a result, you can claim compensation.

The evidence you gather proves these elements. Medical records prove harm. Your booking email proves you warned them. The undeclared allergen proves breach. Witness statements prove causation—you told them, they assured you, you reacted anyway. Each piece of evidence addresses a specific legal requirement.

The Burden of Proof Standard

You need to prove your claim on the “balance of probabilities”—more likely than not. This is the civil standard, not the criminal standard of “beyond reasonable doubt.” If your evidence tips the scales 51% in your favour, you win. This matters because you don’t need perfect proof—you need sufficient proof.

After handling hundreds of nut allergy claims since 2007, we know that “imperfect” evidence often proves perfectly adequate. The packaging’s in the bin? Medical records might carry it. No witness? Contemporaneous texts to your partner count. The law doesn’t demand perfection—it demands probability.

Why Evidence Timing Matters

Evidence degrades. CCTV systems typically retain footage for 7-30 days before automatic deletion. Staff memories fade within weeks. Witnesses change jobs and become untraceable. Food samples degrade unless properly preserved. The longer you wait, the harder your claim becomes.

You have three years from the date of your reaction to start legal proceedings (the “limitation period”), but don’t mistake that for how long you should wait. Wondering if it’s too late to claim for a reaction years ago? Not necessarily—discretion exists for valid reasons. The strongest claims we handle are those where evidence was preserved immediately. The weakest are those where months passed before anyone thought to collect proof.

Why Evidence Matters – What You’re Actually Proving

What Makes a Winning Claim

You’re not just proving you had a reaction. You’re building a legal claim that connects four specific dots: duty, breach, causation, and damage. The restaurant owed you a duty of care. They breached it by exposing you to nuts despite your warning. That breach caused your reaction. The reaction caused measurable harm. Miss one dot, the line doesn’t connect.

Evidence maps directly onto each element. Medical records prove the damage. Your booking email mentioning “severe peanut allergy” proves you gave fair warning. The packaging with undeclared allergens proves the breach. Witness statements tie it all together—you warned them, they assured you, you reacted anyway.

The Standard That Actually Matters

Here’s what most people get wrong: you don’t need to prove your claim “beyond reasonable doubt” like in a criminal trial. That’s the police’s job when someone breaks the law. You need to meet the civil standard—”balance of probabilities.” More likely than not. 51% certain. If the evidence tips the scales even slightly in your favour, you win.

This matters enormously for evidence gathering. You don’t need perfect proof. You need enough proof. The packaging’s in the bin? Your medical records might be enough. No witness? Your contemporaneous text to your partner saying “told the waiter about my allergy” counts. After 17 years handling these claims, we’ve learned that “imperfect” evidence often proves perfectly adequate.

Consider a scenario where someone has thrown away packaging but their GP notes from the next day combined with their booking email mentioning allergies create sufficient evidence. The civil standard doesn’t demand perfection—just probability.

Why Insurers Challenge Everything

Food business insurers know something you don’t yet: most people give up when challenged. They’ll question your medical records. They’ll claim you didn’t warn their staff clearly enough. They’ll suggest you ate nuts knowingly. Not because they believe it—because it works. People without proper evidence fold.

We’ve seen every tactic.The “training records” that suddenly appear showing staff were “fully trained” (they weren’t). The most common defence is when the business denies you told them about your allergy, but strong evidence shuts this down. The witness statements from staff who “don’t remember” you mentioning allergies (you did). The attempt to blame you for not checking thoroughly enough (their legal duty, not yours). Strong evidence shuts these tactics down before they start. Weak evidence—or worse, missing evidence—gives them ammunition.

Medical Evidence – The Foundation of Your Claim

A&E Attendance – The Gold Standard

Hospital records trump everything. Allergic reactions are medical emergencies—if you attended A&E, you’ve got documentation of timing, symptoms, treatment, and severity. The triage notes showing “patient reports restaurant peanut exposure” prove causation. The prescription for antihistamines or steroids proves you genuinely reacted. The discharge letter quantifies severity.

Medical records proving your reaction. A&E attendance notes. GP consultation records. Ambulance call logs. Pharmacy receipts for antihistamines. Even an EpiPen prescription from weeks earlier matters—proves you’re genuinely allergic, not just claiming it now.

Real example: We’ve won numerous claims where A&E records were the primary evidence. Even with gaps elsewhere—no menu photos, no witnesses—strong hospital documentation often leads to quick settlement. Insurers know contemporaneous medical records are hard to challenge. A&E attendance can change everything.

GP Consultations and Follow-Up Care

Saw your GP the next day? Those notes matter. Documented your symptoms. Recorded your account of what happened. Noted ongoing issues—anxiety about eating out, digestive problems, sleep disruption from the experience. All compensable. All provable through medical records.

Even routine GP visits before your reaction help. Previous prescriptions for EpiPens prove pre-existing allergy. Previous consultations discussing management prove you take it seriously. Establishes you’re not someone who’d knowingly eat nuts.

What If You Didn’t Seek Medical Attention?

Honestly, this weakens your claim significantly. Not fatally—we’ve won without—but you’re fighting uphill. Insurers argue “couldn’t have been that serious if you didn’t see a doctor.” Frustrating? Yes. Unfair? Often. Reality? Absolutely.

If you didn’t go to hospital but bought antihistamines from a pharmacy, we can sometimes obtain records through the pharmacy. If you told your GP about it later, those records help. If you genuinely couldn’t seek help immediately—perhaps you were miles from anywhere—we work with what we have. But we won’t pretend it’s not a challenge.

How We Obtain Medical Records You Don’t Have

You don’t need to request everything yourself. We handle medical records requests as part of your claim. GP records, hospital notes, ambulance service logs—we know exactly what to request and how to request it. Most arrive within 28 days. Some take longer. We chase them. You focus on recovering.

Proving What You Ate – Food and Packaging Evidence

Why Packaging Matters So Much

That container you nearly threw away? It’s potential gold. Batch codes trace back to suppliers. Ingredient lists show what should’ve been declared. “May contain” warnings prove knowledge of contamination risk. Even the absence of warnings matters—Trading Standards prosecutions have been won on missing allergen labels alone.

Sometimes packaging seems lost but alternatives emerge. When restaurants have been prosecuted by local authorities for the same dish previously, those prosecution records become your evidence. Previous incident reports can demonstrate a pattern of poor allergen management. We’ve secured settlements without original packaging by proving the restaurant had form.

Food Samples – Handle With Extreme Care

If you’ve kept actual food, refrigerate it immediately. Sealed container. Don’t freeze—changes composition. Some people worry this seems excessive. It’s not. Independent laboratory testing sometimes proves undeclared allergens. If the restaurant claims they “never use nuts,” a lab report showing peanut proteins ends that argument instantly.

But here’s the reality: most people eat their food or bin it. Completely understandable. We work around it. You’d be surprised how often the restaurant’s own records show what you ate—and what was in it.

Receipts and Payment Proof

Your receipt proves three things: you were there, you ate on that date, you ordered that specific dish. If you paid by card, your bank statement backs it up. Seems basic? Insurers still challenge it. “How do we know you ate there? Could’ve been anyone’s receipt.”

Digital payment trails are even better. Contactless payment, app-based ordering, online booking with pre-payment—all timestamped, verified, impossible to fabricate. The forensic trail matters when insurers look for excuses.

Delivery App Orders – Underused Goldmine

Ordered through Deliveroo? Uber Eats? Just Eat? Those apps store complete order histories. What you ordered. When. From where. Special instructions—like “NO NUTS – SEVERE ALLERGY” in the notes section. Screenshot everything before contacting us. Apps sometimes delete order history after 90 days.

What If You Really Don’t Have Packaging or Receipts?

We’ve won without. Menu photographs help—proves what was available and how allergens were (or weren’t) labelled. Booking confirmations help—proves you were expected, sometimes with dietary requirements noted. Bank statements help—proves transaction even without itemised receipt.

But we’re honest: it’s harder. We’re investigating rather than proving. Takes longer. Requires more work from us. Sometimes fails. We tell you straight during your free assessment whether we think the evidence gaps are surmountable. If they’re not, we say so. We don’t take claims we don’t believe in.

Business Records You Can Obtain – Evidence They Think You Can’t Access

Subject Access Requests Under GDPR

The restaurant holds records about you—and they must provide them. Subject Access Requests (SARs) under GDPR 2018 give you the right to see any data they hold relating to you. Free of charge. Within one month.

What you can request: Your booking details (including any allergy notes), order records, complaint correspondence, staff incident reports mentioning you, CCTV footage showing you (if it still exists), payment records, and any internal communications about your reaction. They must provide everything they hold about you—even emails between managers discussing “that allergic reaction yesterday.”

Allergen Information and Training Records

Restaurants must keep allergen matrices showing which dishes contain which allergens. They must document staff training on allergen management. They must retain supplier specifications proving ingredient content. All of this becomes your evidence.

Consider a situation where a restaurant claims their staff were “fully trained” and “you never mentioned allergies.” Their own training records show the last allergen training was 18 months ago – should have been refreshed. Their incident log shows three previous nut allergy reactions in the past year. Suddenly their credibility evaporates.

Environmental Health and Trading Standards Reports

Local authorities inspect food businesses regularly. Those inspection reports are public records. We obtain them as standard. Food hygiene ratings, improvement notices, previous warnings about allergen management—all documented, all available, all useful.

If the restaurant has been prosecuted previously for allergen breaches, those prosecution records strengthen your claim enormously. Pattern of negligence. Established poor practice. Knowledge of the risk. Courts take this seriously.

Previous Incident Reports and Insurance Claims

This is where it gets interesting. If other people have had allergic reactions at the same establishment, there will be records. Insurance companies keep meticulous logs. We can sometimes obtain (through legal disclosure processes once your claim is underway) evidence of previous similar incidents.

Multiple victims create powerful evidence of systemic failure. One person’s reaction might be dismissed as “unfortunate.” Three people? That’s negligence. Five people? That’s a business that learned nothing from repeated mistakes.

CCTV Footage – The 30-Day Window

Most commercial CCTV systems retain footage for 7-30 days before automatic deletion. After that, it’s gone forever. This is why immediate action matters so much.

CCTV can prove: you were there, you spoke to staff (even if it can’t capture audio, body language shows conversation), your visible reaction (facial swelling, distress), the food you received, and critically—whether that “warning sign” they claim existed was actually visible. CCTV may show nothing of the sort.

Where appropriate we request CCTV preservation immediately upon instruction. Legal letter stating footage must be retained as evidence. Most comply. Some “accidentally” delete it anyway—which tells its own story to a judge.

How We Handle the Evidence Gathering

You don’t chase these records yourself. We do it. Subject Access Requests, Environmental Health enquiries, local authority records, supplier specifications, training documentation—we know what to request, how to request it, and when to escalate if they stall.

After 17 years handling nut allergy claims, we’ve learned how best to gather all the evidence we need to establish liability and causation. We know how to extract maximum evidence with minimum delay. This is what we do. You focus on recovering. We focus on building your claim properly.  

Why People Choose Carter & Carter for Nut Allergy Claims

After 17 years handling nut allergy claims, we’ve learned something most firms miss: evidence gathering isn’t about checklists—it’s about knowing which evidence actually matters to insurers. That expertise doesn’t come from a training manual. It comes from doing this hundreds of times.

Here’s what that means in practice: When insurers challenge your evidence (and they will), you’re not explaining yourself to someone reading from a script. You’re talking to the solicitor who knows your case inside out—because they’ve handled it from day one.
